Default External fuelpump

I have a walbro 255 lph fuel pump.. gonna upgrade my injectors and wondering if the pump would be able to support it... If not.. just wondering if putting an external pump on with the in tank pump would be good and.. wondering on how I hook it up.. Do I hook it up through the factory fuel line with the walbro in place?

What injectors you plan on running and how much boost?

Im running the Custom 72# from SRT10KLLR with a 2yr old Intank Walbro 255 on 5#boost and a 50 shot.. i plan on upping it to 10# boost when i get time to dail in my fuel table..

A inline isnt goin to help much cause its only goin to flow what the intank can supply the inline with..
